  • the UE VoIP engine monitors the network pattern periodicity and implements a scalable scheduling strategy that can adapt the VoIP scheduling to the current local radio configuration in one embodiment. By adapting its scheduling, the VoIP engine can reduce mouth-to-ear delay or power consumption while keeping the audio transmission rate constant.
  • the lower telecommunication radio layer (data link) is kept independent from an upper layer (transport/application). It is possible for the lower layer to notify upper layers about the current CDRX cycle delay or the current SPS period value or to expose an application program interface (API) to set data link layer's preferences.

  • the best trade-off between mouth-to-ear delay and power consumption of a Voice over Long Term Evolution (VoLTE) call is identified.
  • UE may be allowed to indicate to the network its preferred CDRX or SPS state for voice, based on UE latency, power performance or any other proprietary or device preference stored in the UE settings or computed at run time.
  • the UE When connecting to a new network base station base station, the UE may provide its voice CDRX cycle or SPS period preference.
  • the network base station may not support or may ignore the UE preference.
  • the UE preference can be followed by the network base station when the network base station has no particular preference.
  • the UE preference may be based on criteria set by the manufacturer of the device.
  • the UE equipment vendor suggests to the network network base station a configuration that is optimal for the device. For instance, for a device providing very good latency performance, the manufacturer may decide to request to use a network configuration that is more power efficient, i.e. a longer period CDRX cycle or SPS period, at the expense of a mouth-to-ear delay penalty.
  • the preference can also be set dynamically based on Real-time Transport Control Protocol (RTCP) measurements, VoIP Round Trip Time measurements, latency measurements or Jitter Buffer Management statistics which can indicate a good mouth-to-ear delay, and so the delay can be increased without any noticeable impact on the user experience. Therefore a UE can suggest a higher CDRX or SPS cycle. In other situations the UE can suggest a smaller CDRX or SPS if it detects a degradation of the voice quality.
  • RTCP Real-time Transport Control Protocol
  • the UE VoIP engine monitors the current CDRX cycle or SPS period configuration. Based on this information, the VoIP engine adapts the VoIP engine scheduling rate, the audio driver data transfer scheduling rate, and the RTP aggregation rate to match the network periodicity. Matching the network periodicity avoids useless over-scheduling and achieves better network bandwidth usage when the network periodicity is large, and avoids penalizing mouth-to-ear delay when the network periodicity is small.
  • a better power/mouth-to-ear trade-off on the UE may be obtained by having the UE suggest a preferred CDRX or SPS cycle to the network in order to influence the network to an optimal configuration for this particular UE based on some intrinsic performance of the UE or based on some UE run-time statistics monitoring such as round trip delay, link quality or transmission signal level. Also, a better trade-off can be determined by matching the VoIP engine scheduling period to the network periodicity, which includes matching the VoIP engine scheduling rate, transfer rate of read/write from/to audio driver, and scheduling rate of packet sending with network periodicity.

  • Modem settings may be configured to customize the preferred UE Voice Scheduling Period according to some UE overall latency, or power performance.
  • the UE LTE data link layer exposes a high level interface that notifies clients about the initial value and value change of CDRX cycle and SPS period. It also provides an interface indicating the average time difference packet Uplink Staging Duration between the moment where the UE VoIP engine sends the packet to the UE data link layer and the On Duration period when the packet is transmitted to the base station.
  • the UE VoIP engine monitors the network current scheduling periodicity in order to match its scheduling period and audio driver data transfer period with the current network scheduling periodicity.
  • the VoIP engine is capable of controlling the delay between packet reception and driver frame write operation by configuring audio and jitter buffer sizes to a value large enough to decode the frames included in the RTP packet(s), to absorb system latencies and to cancel the network jitter.

Abstract

Selon l'invention, le moteur VoIP d'équipement utilisateur (UE) surveille la périodicité de motif de réseau et met en œuvre une stratégie de planification évolutive qui peut s'adapter au moteur VoIP et une planification de pilotage audio sur la configuration radio locale actuelle dans un mode de réalisation. En adaptant sa planification, le moteur VoIP peut réduire un temps d'attente ou une consommation d'énergie sans impacter la qualité de codage audio. Le moteur VoIP d'UE envoie certaines préférences de planification à la station de base de réseau. La station de base de réseau surveille des préférences d'UE et décide d'ignorer ou d'accepter des préférences d'UE et permet à l'UE de fonctionner dans les conditions qui fournissent le meilleur compromis entre la consommation d'énergie et le temps d'attente.
